Briana has 4 1/2 cups of oats. She uses 2 1/4 cups of oats to make oatmeal- raisins cookies, then borrow 1 cup of oats from her

insens350 [35]

Answer:

She has enough with $\frac{3}{4}$ cups left over.

Step-by-step explanation:

For this equation, it's probably easiest to use improper fractions.

At the start, she has 4 $\frac{1}{2}$ cups, or $\frac{9}{2}$ , which can be converted to $\frac{18}{4}$ (which is useful for the next part) by multiplying the numerator and denominator by 2.

When she uses 2 $\frac{1}{4}$ cups, which can be converted to $\frac{9}{4}$ . When subtracting this from the original, you get $\frac{18}{4}$ - $\frac{9}{4}$ = $\frac{9}{4}$ .

She borrows another cup, or $\frac{4}{4}$ of a cup, which gets added on to the previous result, giving $\frac{9}{4}$ + $\frac{4}{4}$ = $\frac{13}{4}$ .

The recipe calls for 2 $\frac{1}{2}$ cups, which can be converted to $\frac{5}{2}$ or $\frac{10}{4}$ .

$\frac{13}{4}$ - $\frac{10}{4}$ = $\frac{3}{4}$ , meaning she has $\frac{3}{4}$ cups left over.

** solving this mainly uses conversion to improper fractions and adding/subtracting fractions, which may be skills you would like to practice. I'm always happy to help!
